VALVE FOR BOTTLES.

SPECIFICATION forming part of Letters Patent No. 580,979, dated April20, 1897. Application filed January 25, 1896. Serial No. 576,794. (Nomodel.)

To all whom t may concern:

Be it known that I, HENRY GERD LOHMAN, a citizen of the United States,and a resident of Mount Vernon, in the county of Vestchester and Stateof New York, have invented certain new and useful Improvements in Valvesfor Bottles or other Vessels, of which the following is a specification,reference being had to the accompanying drawings, forming a partthereof, in which similar letters of reference indicate correspondingparts.

This invention relates to bottles, jugs, jars, and similar vessels, andthe object thereof is .to provide a vessel of this class which havingbeen once filled cannot be emptied of its contents without leavingevidence of the fact, a further object being to provide a bottle orother vessel which is adapted to be filled through the side of the upperportion thereof and which is provided with a neck attachment having acentral passage therethrough provided with automatic valves which are soconstructed and arranged that they will operate to admit of thedischarge of the contents of the vessel and also to prevent therefilling thereof.

The invention is fully disclosed in the following speciiication, ofwhich the accompanying drawings form a part, in which- Figure l is aCentral vertical section of the upper part of a bottle provided with myimprovement; Fig. 2, a section on the line 2 2 of Fig. l, and Fig. 3 asection on the line 3 3.

In the drawings forming part of this speci-l fication Ihave shown myinvention applied to a bottle, and in the practice thereof I provide abottle or other vesselA, having a neck B, the walls of which arepreferably slightly inclined inwardly and downwardly from the topthereof, and the upper end of the neck is closed, as shown at l), andprovided with side ports or openings b2. I also provide a plug orstopper O, which is composed of cork cr other preferred material, andthrough which passes a tubular or hollow attachment D. The attachment Dis composed of metal, and formed near the lower end thereof is anannular enlargement d, below which is a contracted valve-seat d2,adapted to receive a valve G, to the lower side of which is secured arod g, which passes through a keeper or guide g2, secured transverselyof the lower end of the attachment, and between said keeper or guide andsaid valve is a spiral spring g3.

At a predetermined distance above the annular enlargement cl of theattachment D is a contracted annular valve-seat H, on which is placed avalve h, to the lower side of which is secured a rod h2, the lower endof which passes through a spider or keeper h3 and on which is mounted aspiral spring h4, and pivotally connected to the spider or keeper h3 atone side 0f the center thereof is a curved arm or lever K, the lower endof which bears upon the upper side of the valve G between two guides lo,which are best shown in Fig. 2, and the upper end of said arm or leveris provided with an inwardly-directed projection 7c3, which operates inconnection with a lug or projection 7a4, formed on the side of the rodh2.

Above the valve-seat H there is a slight annular enlargement in thetubular attachment D, as shown at L, at the upper side of which areformed inwardly-directed plates or projections M, and secured within theupper portion of the tubular attachment D is a vertical plate orprojection fm, at the upper edge of which are outwardly-directed prongsor projections m2, and the upper end of the tubular attachment D isprovided with a flange or rim m3, which covers the upper end of the plugor stopper O.

It will lbe observed that the upper end of the plug or stopper O islevel with the botdevice is secured within the neck of the bottle at thetime of its construction and may be secured therein or connectedtherewith in any desired manner, and I also provide a small port 0ropening O, which is preferably located in the upper end of the bottle orvessel and which is adapted to be sealed by a glass plug or otherstopper O2 after the bottle or vessel has been filled, or said port oropening may be sealed or closed in any desired manner, the only objectin' this connection being to hermetically close said port or opening sothat it cannot be reopened.

The operation will be readily understood from the foregoing descriptionwhen taken in connection with the accompanying drawings.

tom of the side ports or openings b2, and this After the bottle has beenfilled and the port or opening O sealed, as described, the side ports oropenings h2 in the neck may be closed in any desired manner by plugs orStoppers, or in any other way, and when it is desired to empty thebottle or discharge a portion of its contents said plugs or stoppers areremoved and the bottle or vessel is iiiverted or tilted and the valves Gand 7L will leave their seats under the pressure of liquids within thebottle and the action of gravity,

and the said liquids will ilow out through the tubular attachment D andout through the side ports or openings h2, or one of them, and thisoperation may be continued or repeated until the vessel is entirelyemptied. It will be understood, of course, that the lower valve G willbe the first to leave its seat, and the arm or lever K is operated bythis valve in such manner as to withdraw the projection L thereof fromits connection with the lug or projection 7Jl on the rod 7b2, afterwhich the valve 7L will also lea-ve its seat under pressure of liquidswithin the bottle and the operation of gravity, and when the bottle hasbeen emptied or the operation of discharging the contents thereofconcluded and the bottle returned to a vertical position the said valveswill each be reseated and the lever or arm K will resume the positionshown iii Fig. l.

It will be understood that the springs g3 and 7L are contractile springsand serve in the normal position of the bottle to retain the valves inplace; but these springs aie so adjusted as to be bai'ely sufficient forthis purpose, and the pressure necessary to operate the valves is veryslight.

The object of the upwardly and inwardly directed prongs or plates M, thepartition m, and the prongs or projections m2 at the top thereof is toprevent the insertion of a tool, wire, or other iiistiiiineiit in anattempt to interfere with the operation of the valves, and it is evidentthat changes in the construction herein described and modificationsthereof may be made without departing from the spirit of my invention orsacrificing its advantages.

I am aware that valves have been devised for the purpose of preventingrefilling of bottles after once emptying the saine, but iii these easestwo valves were used and connected by a permanent rod or fixture in sucha manner that they operate simultaneously, uncovering openings to allowoutward passage of liquid, but become firmlyseated when an attempt ismade to refill the saine by outward pressure. It is found, however, thatby producing a partial vacuum from the outside of the valve after thebottles are emptied the valve can be unseated, and by carefulmanipulation the bottle can by gradual introduction of liquid berefilled. In my invention this difficulty is entirely obviated, inasmuchas the outer valve when locked cannot be released or raised withoutfirst raising the inner valve, and as no vacuum can be produced near theinner valve to raise the first to release the iii-st valve it willreadily be seen that said valve cannot be unseated in the mannerheretofore adopted.

Having fully described my invention, I claim as new and desire to secureby Letters Patent- I. A bottle or other vessel provided with a neck, theupper end of which is closed and provided with side ports or openings, aplug or stopper secured within said neck below said ports or openingsthrough which passes a tubular or hollow attachment near the lower endof which is a valve-seat, and a valve adapted to be seated thereon, saidtubular attaeliineiit being also provided about midway between saidvalve and the upper end thereof,with an other valve-seat, and a valveseated thereon, each of said valves being provided with a rod, whichpasses through a keeper or spider, and on which is mounted a springwhich operates to retain the valve upon its seat, and a pivoted arm orlever tlielower end of which rests upon the lower valve and the upperend of which is provided with a projection which operates iii connectionwith a lug or projection formed on the rod connected with the uppervalve, substantially as shown and described.
